What is the recommended technique for using a 1 mL 1:1000 (0.1 %) adrenaline (epinephrine) soaked gauze to control anterior epistaxis in adults, including contraindications and next steps if bleeding persists?

Adrenaline-Soaked Gauze for Epistaxis Management

Adrenaline (epinephrine) 1:1000 soaked gauze is not the first-line treatment for anterior epistaxis and should only be considered after initial manual compression fails, with oxymetazoline spray being the preferred topical vasoconstrictor when pharmacologic intervention is needed. 1

Initial Management: Manual Compression First

• The patient should sit upright with head tilted slightly forward (not backward) and apply firm, continuous pressure to the lower third (soft portion) of the nose for 10-15 minutes without releasing pressure to allow clot formation 2, 1
• Breathing should occur through the mouth while spitting out blood rather than swallowing it 2, 1
• Nasal pressure alone controls bleeding in approximately 80% of cases, making it sufficient as initial therapy in the vast majority of presentations 1

When Topical Vasoconstrictors Are Indicated

If bleeding persists after 15 minutes of continuous manual pressure, topical vasoconstrictors should be considered 1:

Preferred Agent: Oxymetazoline

• Oxymetazoline nasal spray is superior to epinephrine-lidocaine combinations for achieving rapid hemostasis and reducing recurrence rates 3
• In a 2025 prospective study, oxymetazoline achieved hemostasis in 71% of patients who failed pressure therapy, compared to only 49% with epinephrine-lidocaine (p=0.007) 3
• Application technique: Clear clots by having patient blow nose, spray 2 sprays into bleeding nostril, then continue holding soft part of nose for 5 minutes; may repeat once 4

Epinephrine-Soaked Gauze: Secondary Option

• A 2022 randomized controlled trial found no significant difference in bleeding stop times between topical lidocaine, epinephrine, and tranexamic acid (p=0.870 for lidocaine vs. epinephrine) 5
• When epinephrine is used, the typical concentration is 1:10,000 dilution (not 1:1000) for topical nasal application to minimize systemic absorption and cardiovascular effects 6
• The 1:1000 concentration mentioned in the question is too concentrated for routine topical nasal use and carries increased risk of systemic effects including hypertension and tachycardia 5

Technique for Topical Vasoconstrictor Application

When using any topical vasoconstrictor on gauze or packing 1, 6:

1. Apply local anesthetic first if cautery will follow
2. Soak gauze or packing material with the vasoconstrictor solution
3. Place directly at the bleeding site for 8-10 minutes
4. Limit application to the active bleeding site only to minimize tissue injury 1
5. Monitor blood pressure, as epinephrine can cause significant hypertension 5

Contraindications and Precautions

Relative Contraindications to Epinephrine

• Uncontrolled hypertension: Epinephrine caused statistically significant increases in both systolic and diastolic blood pressure compared to other agents 5
• Severe coronary artery disease or recent myocardial infarction (systemic absorption risk)
• Patients on MAO inhibitors or tricyclic antidepressants (drug interactions)

Special Populations

• Patients on anticoagulants/antiplatelets: Use resorbable packing materials and attempt local hemostatic measures before considering anticoagulation reversal 1
• Patients with bleeding disorders: Resorbable packing is preferred over non-resorbable materials 1

Next Steps If Bleeding Persists

Escalation Algorithm 1:

1. If bleeding continues despite topical vasoconstrictors: Apply nasal cautery with silver nitrate to the identified bleeding site only 1, 7

   • Silver nitrate cauterization has an 80% success rate for anterior epistaxis 7

2. If bleeding source cannot be identified: Place nasal packing (resorbable preferred in anticoagulated patients) 1

   • Merocel wrapped with Surgicel has shown effectiveness for diffuse bleeding 8

3. If bleeding persists despite packing and cautery: Perform nasal endoscopy to locate the bleeding source 1

4. Refractory cases: Consider surgical arterial ligation (endoscopic sphenopalatine artery ligation) or endovascular embolization 1

When to Seek Emergency Care

Immediate medical attention is required if 2, 1:

• Bleeding does not stop after 15 minutes of continuous manual pressure
• Patient becomes lightheaded from blood loss
• Epistaxis is associated with trauma showing signs of brain injury, nasal deformity, or facial fracture
• Patient is on anticoagulants/antiplatelets and bleeding has not completely ceased

Critical Pitfalls to Avoid

• Do not tilt head backward: This directs blood toward the airway and stomach 1
• Do not use 1:1000 epinephrine concentration topically: Use 1:10,000 dilution if epinephrine is chosen 6
• Do not apply broad cauterization: Limit to the active bleeding site only to prevent tissue damage 1
• Do not immediately discontinue anticoagulation: Attempt local hemostatic measures first unless bleeding is life-threatening 1
• Cryotherapy (ice) lacks evidence: Not supported as a primary treatment modality 2, 1

Documentation Requirements

• Document intervention outcomes within 30 days for patients treated with non-resorbable packing, surgery, or arterial ligation/embolization, or document transition of care 4, 1
• Record type of packing used, expected removal schedule, and patient education provided 1
